The utility model relates to a mower structure, which comprises: a mower blade is a rectangle, rhombus or other geometry with appropriate length width ratio and narrow shape； the blade mainly has more than two straight edges or oblique straight edges, and the main straight edges or oblique straight edges form equispaced or unequal spaced V-shaped, U-shaped or arc-shaped notches, and the V-shaped, U-shaped or arc-shaped notches are arranged. A V-shaped, U-shaped or arc-shaped notch cutting edge is formed by setting an inclined plane inward.According to this, when cutting weeds, the gap cutting blade at intervals can effectively and effortlessly cut weeds, and it will not cause the problem that the circular serrated blade is easy to jam grass scraps, and it is convenient to cut weeds with irregular angles due to the growth of the environment, which can effectively improve the effect that the conventional mowing blade cannot achieve, and it is very convenient to use.一種割草刀結構，係包含有：一割草刀片係為適當長寬比且呈現狹長形的長方形、菱形或其他狹長、多片狹長的幾何形狀；該刀片主要具有二以上的平直刃部或斜直刃部，主要平直刃部或斜直刃部上形成等間隔或不等間隔且設置一以上的V形、U形或弧形缺口，前述V形、U形或弧形缺口往內並設斜面形成V形、U形或弧形缺口切刃。據此，割除雜草時，間隔的缺口切刃可有效且省力割除雜草，也不會產生如圓形鋸齒刀容易卡草屑的問題，且方便割除因環境生長而長出不規格角度之雜草，有效改善習知割草刀片所無法達到的功效，深具使用便利性者。
